Clinicopathologic characteristics and outcomes of prostate cancer incidentally discovered at the time of radical cystoprostatectomy: a population-based cohort study.	OBJECTIVE: This study aimed to comprehensively analyze the clinical characteristics and prognosis of patients with concomitant bladder cancer (BCa) and prostate cancer (PCa) using a large population-based database. METHODS: Within the Surveillance, Epidemiology, and End Results (SEER) database (2000-2019), the authors identified patient with concomitant PCa at the time of radical cystoprostatectomy (RCP). Logistic regression and propensity score matching (PSM) analyses were employed to identify risk factors and mitigate confounders, respectively. Kaplan-Meier survival curves were used to estimate cancer-specific survival (CSS). RESULTS: A total of 14 199 BCa patients undergoing RCP were identified, with 28.8% incidentally discovered to have concurrent PCa. Among them, 89.9% exhibited organ-confined (T1-2) PCa. An increased risk of concomitant tumors was observed among older age, white race, and high tumor grade of BCa. Survival analysis revealed no significant difference in CSS between patients with BCa alone and those with concurrent PCa (5-year CSS rate: 71.3 vs. 67.2%, P =0.076). Subgroup analysis and multivariable analysis, however, indicated that concurrent high-risk PCa adversely impacted survival (5-year CSS rate: 71.3 vs. 63.4%, HR 1.27, 95% CI: 1.01-1.58, P =0.038) compared to solitary BCa. Notably, the presence of low/intermediate-risk PCa did not affect survival outcomes ( P =0.584). CONCLUSION: In conclusion, incidentally discovered PCa in RCP specimens is frequent and characterized by organ-confined presentation, lower PSA levels, and Gleason scores. Patients with concurrent high-risk PCa have a worse prognosis compared to those with solitary BCa, while the presence of low/intermediate-risk PCa does not influence oncological prognosis.	bladder
Unlocking the Therapeutic Potential of LncRNA BLACAT1 in Hypopharynx Squamous Cell Carcinoma.	BACKGROUND: Identifying the key molecular targets in hypopharynx squamous cell carcinoma (HSCC) is crucial for understanding this prevalent and highly fatal type of head and neck tumor. The study aims to enhance comprehension of the HSCC process by accurately identifying these key molecular targets. MATERIALS AND METHODS: In this study, we examined 47 clinical tissue samples from individuals diagnosed with HSCC using RNA-seq high-throughput assay. Quantitative real-time PCR (RT-PCR) was used to compare long non-coding RNA (lncRNA) bladder cancer-associated transcript 1 (BLACAT1) expression in HSCC tissues versus adjacent non-tumor tissues. The influence of highly expressed lncRNA BLACAT1 on prognostic survival was assessed. Subsequently, we cultured human pharynx squamous cell carcinoma FaDu cells. After reducing lncRNA BLACAT1 expression, we assessed FaDu cell proliferation, invasion, and migration using Cell Counting kit-8 (CCK-8) assay, colony formation assay, EUD assay, Transwell assay, and scratch assay. Additionally, liquid chromatography-tandem mass spectrometry/mass spectrometry (LC-MS/MS) and western blotting analysis were used to analyze proteins that bind to lncRNA BLACAT1. During in vivo experiments, mice received subcutaneous injections of FaDu cells transfected with lncRNA BLACAT1 shRNA or Scr plasmid (Control) in the dorsal region to observe and compare tumor growth. Lastly, tumor tissues underwent hematoxylin-eosin (HE) and immunohistochemical (IHC) staining. RESULTS: lncRNA BLACAT1 was screened as one of the most significant genes among the group of differentially expressed lncRNAs. RT-PCR exhibited elevated lncRNA BLACAT1 expression in HSCC tissues when compared to non-tumor tissues (p < 0.001). Furthermore, increased lncRNA BLACAT1 expression correlated with advanced clinical stages, heightened lymphatic invasion, and a poor prognosis. Subsequent in vitro experiments solidified our observations, demonstrating lncRNA BLACAT1's promotion of HSCC cell proliferation (p < 0.05), migration (p < 0.01), and invasion (p < 0.01) compared with the control group. Moreover, LC-MS/MS identified signal transducer and activator of transcription 3 (STAT3) and Prohibitin 2 (PHB2) as lncRNA BLACAT1-binding proteins and sh-lncRNA BLACAT1 inhibits STAT3/AKT phosphorylation (p < 0.01) and alters the subcellular distribution of PHB2 and P21 compared with the control group (p < 0.01). Moreover, in vivo experiments showed that lncRNA BLACAT1 inhibition suppresses tumorigenicity in an HSCC xenograft model compared to the control group (p < 0.01). CONCLUSIONS: lncRNA BLACAT1 is highly expressed in HSCC tumor tissues and plays a crucial role in the development of HSCC in vitro and in vivo. This increased expression may be caused by STAT3/AKT pathway activation, consequently inhibiting P21 expression through PHB2.	bladder
Nomogram for customized recurrence prediction in primary non-muscle-invasive bladder cancer based on routine blood and urine parameters.	PURPOSE: A prevalent condition with a high probability of recurrence, non-muscle invasive bladder cancer (NMIBC) necessitates lifetime surveillance. In patients with pathologically confirmed NMIBC, our goal was to create a unique nomogram to predict recurrence after transurethral resection of bladder tumor (TURBT). METHODS: Our institution's 91 NMIBC patients with complete follow-up data between January 2017 and February 2021 were included in the retrospective analysis. The nomogram predicting the 0.5, 1, 2 and 3-year likelihood of recurrence was created using multivariate Cox proportional hazard models to find the significant determinants of recurrence. Using the concordance index (C-index), calibration curves, receiver operating characteristic (ROC) curves, and decision curve analyses (DCA), we internally validated the nomogram. RESULTS: The significant factors related to NMIBC recurrence were age, blood platelet count, especially for the urine leukocyte count and mucus filament. The constructed nomogram performed well in the customized prediction of NMIBC recurrence at 6th, 12th, 24th and 36th month, of which the C-index was 0.724. The calibration curve and the ROC curve both validated the prediction accuracy. On DCA, the nomogram presented good net benefit gains across a wide range of threshold probabilities. Furthermore, the Nomogram-related risk score was used to divide the patient population into two groups with significant recurrence disparities. CONCLUSION: For the prediction of NMIBC recurrence, our unique nomogram demonstrated a respectable degree of discriminative capacity, sufficient calibration, and considerable net benefit gain. There will be a need for additional internal and external validation.	bladder
Updates on Urinary Bladder Tumors With Neuroendocrine Features.	The most common neuroendocrine tumor in the urinary bladder is small cell carcinoma, which can be pure or mixed with components of urothelial or other histologic subtypes. Large cell neuroendocrine carcinoma of the bladder is rare and remains ill-defined but is increasingly recognized. Well-differentiated neuroendocrine tumor and paraganglioma can arise in the bladder but are very rare in this location. Recent advances in molecular characterization allowed for better classification and may offer improved stratification of these tumors.	bladder
Transurethral Resection of Bladder Tumor Outcomes Are Predicted by a 5-Item Frailty Index.	OBJECTIVE: To evaluate the mFI-5 as a predictor of postoperative outcomes following transurethral resection of bladder tumor (TURBT). METHODS: The National Surgical Quality Improvement Program database was queried for TURBT cases from 2015-2019. mFI-5 scores were calculated by assigning a point to chronic obstructive pulmonary disease, congestive heart failure, dependent functional status, hypertension, and diabetes. Patients were stratified by mFI-5 scores. Demographics and 30-day outcomes including Clavien-Dindo (CD) complications, mortality, and increased healthcare resource utilization (HCRU) were compared. HCRU outcomes included prolonged length of stay, unplanned readmission, and discharge to continued care. Multivariate regression assessed the predictive value of mFI-5 scores on outcomes. RESULTS: 40,278 TURBT cases were identified (mFI-5 =0: 12,400, mFI-5 =1: 17,328, mFI-5 =2: 9225, mFI-5 ≥3: 1416). Patients with higher mFI-5 scores were more likely to be older, male, White, and have larger tumors, all P < .05. Increasing mFI-5 scores resulted in increased frequency of all adverse outcomes, all P < .001. On multivariate analysis, mFI-5 ≥ 3 classification was a predictor of CD I/II (OR=1.280), CD IV (OR=2.539), mortality (OR=2.202), HCRU (OR=2.094), prolonged length of stay (OR=2.136), discharge to continued care (OR=3.401), and unplanned readmission (OR=1.705), all P < .05. A mFI-5 ≥ 3 demonstrated a sensitivity ranging from 6.0%-13.5% and a specificity ranging from 96.6%-97.0% for all outcomes. CONCLUSION: The mFI-5 is an easily ascertainable preoperative risk assessment tool that is a predictor of adverse clinical and HCRU outcomes following TURBT.	bladder
Multi-omics comprehensive analysis reveals the predictive value of N6-methyladenosine- related genes in prognosis and immune escape of bladder cancer.	BACKGROUND: N6-methyladenosine (m6A) is the most frequent RNA modification in mammals, and its role in bladder cancer (BC) remains rarely revealed. OBJECTIVE: To predict the value of m6A-related genes in prognosis and immunity in BC. METHODS: We performed multiple omics analysis of 618 TCGA and GEO patients and used principal component analysis (PCA) to calculate the m6A score for BC patients. RESULTS: We described the multiple omics status of 23 m6A methylation-related genes (MRGs), and four m6A clusters were identified, which showed significant differences in immune infiltration and biological pathways. Next, we intersected the differential genes among m6A clusters, and 11 survival-related genes were identified, which were used to calculate the m6A score for the patients. We found that the high-score (HS) group showed lower tumor mutation burden (TMB) and TP53 mutations and better prognosis than the low-score (LS) group. Lower immune infiltration, higher expression of PD-L1, PD-1, and CTLA4, and higher immune dysfunction and immune exclusion scores were identified in the LS group, suggesting a higher possibility of immune escape. Finally, the experimental verification shows that the m6A related genes, such as IGFBP1, plays an important role in the growth and metastasis of bladder cancer. CONCLUSIONS: These findings revealed the important roles of m6A MRGs in predicting prognosis, TMB status, TP53 mutation, immune functions and immunotherapeutic response in BC.	bladder
Bladder cancer: An Update.	Bladder cancer, the 10th most common cancer globally, primarily manifests as urothelial cell carcinoma. Risk factors involve acquired genetic mutations and congenital predispositions, impacting diagnosis and management. This article discusses the risk factors, clinical presentation, and treatment strategies, with emphasis on providing comprehensive nursing support and patient education to patients with bladder cancer.	bladder
Dysregulated FGFR3 signaling alters the immune landscape in bladder cancer and presents therapeutic possibilities in an agent-based model.	Bladder cancer is an increasingly prevalent global disease that continues to cause morbidity and mortality despite recent advances in treatment. Immune checkpoint inhibitors (ICI) and fibroblast growth factor receptor (FGFR)-targeted therapeutics have had modest success in bladder cancer when used as monotherapy. Emerging data suggests that the combination of these two therapies could lead to improved clinical outcomes, but the optimal strategy for combining these agents remains uncertain. Mathematical models, specifically agent-based models (ABMs), have shown recent successes in uncovering the multiscale dynamics that shape the trajectory of cancer. They have enabled the optimization of treatment methods and the identification of novel therapeutic strategies. To assess the combined effects of anti-PD-1 and anti-FGFR3 small molecule inhibitors (SMI) on tumor growth and the immune response, we built an ABM that captures key facets of tumor heterogeneity and CD8(+) T cell phenotypes, their spatial interactions, and their response to therapeutic pressures. Our model quantifies how tumor antigenicity and FGFR3 activating mutations impact disease trajectory and response to anti-PD-1 antibodies and anti-FGFR3 SMI. We find that even a small population of weakly antigenic tumor cells bearing an FGFR3 mutation can render the tumor resistant to combination therapy. However, highly antigenic tumors can overcome therapeutic resistance mediated by FGFR3 mutation. The optimal therapy depends on the strength of the FGFR3 signaling pathway. Under certain conditions, ICI alone is optimal; in others, ICI followed by anti-FGFR3 therapy is best. These results indicate the need to quantify FGFR3 signaling and the fitness advantage conferred on bladder cancer cells harboring this mutation. This ABM approach may enable rationally designed treatment plans to improve clinical outcomes.	bladder
Cross-sectional and longitudinal analyses of urinary extracellular vesicle mRNA markers in urothelial bladder cancer patients.	We designed this multi-center prospective study with the following objectives: (1) the cross-sectional validation of extracellular vesicles (EV) mRNA markers to detect urothelial bladder cancer (UBC) before transurethral resection of bladder cancer (TURBT), and (2) the longitudinal validation of EV mRNA markers to monitor non-muscle invasive bladder cancer (NMIBC) recurrence after TURBT. EV mRNA markers evaluated in this study were KRT17, GPRC5A, and SLC2A1 in addition to two additional markers from literatures, MDK and CXCR2, and measured by quantitative RT-PCR with normalization by a reference gene (ALDOB). Diagnostic performances of EV mRNA markers were compared to conventional markers. Regarding the first objective, we confirmed that EV mRNA biomarkers in urine were higher in UBC patients, particularly those with higher stage/grade tumors, than in those without UBC (n = 278 in total) and the diagnostic performance of EV mRNA MDK and KRT17 outperformed conventional biomarkers with AUC 0.760 and 0.730, respectively. Concerning the second objective, we prospectively analyzed the time courses of EV mRNA markers while NMIBC patients (n = 189) (median follow-up 19 months). The expression of EV mRNA KRT17 was significantly high in patients with recurrence, while it gradually decreased over time in those without recurrence (p < 0.01).	bladder
Sarcopenia is associated with leukopenia in urothelial carcinoma patients who receive tislelizumab combined with gemcitabine and cisplatin therapy.	BACKGROUND: In the era of combination therapy, there has been limited research on body composition. Specific body composition, such as sarcopenia, possesses the potential to serve as a predictive biomarker for toxic effects and clinical response in patients with urothelial carcinoma (UC) undergoing tislelizumab combined with gemcitabine and cisplatin (T + GC). MATERIALS AND METHODS: A total of 112 UC patients who received T + GC were selected at the Affiliated Hospital of Xuzhou Medical University from April 2020 to January 2023. Baseline patient characteristics and detailed hematological parameters were collected using the electronic medical system and laboratory examinations. The computed tomography images of patients were analyzed to calculate psoas muscle mass index (PMI). We evaluated the association between sarcopenia (PMI < 4.5 cm(2)/m(2) in men; PMI < 3.3 cm(2)/m(2) in women) and both hematological toxicity and tumor response. RESULTS: Overall, of the 112 patients (65.2% male, median age 56 years), 43 (38.4%) were defined as sarcopenia. Patients with sarcopenia were notably older (p = 0.037), more likely to have hypertension (p = 0.009), and had poorer ECOG-PS (p = 0.027). Patients with sarcopenia were more likely to develop leukopenia (OR 2.969, 95% CI 1.028-8.575, p = 0.044) after receiving at least two cycles of T + GC. However, these significant differences were not observed in thrombocytopenia and anemia. There were no significant differences in the tumor response and grade 3-4 hematological toxicity between patients with sarcopenia and those without sarcopenia. CONCLUSIONS: Patients with sarcopenia were more likely to develop leukopenia after receiving T + GC. There were no notable alterations observed in relation to anemia or thrombocytopenia. No significant difference was found between the sarcopenia group and non-sarcopenia group in terms of tumor response and grade 3-4 hematological toxicity.	bladder
Chronic pelvic pain and dysmenorrhea disguising a rare submucosal leiomyoma of the urinary bladder.	Representing 0.43% of all urinary bladder neoplasms, leiomyomas are rare mesenchymal tumours with a benign pathophysiology. There have only been approximately 250 cases published on this subject, necessitating further inquiry into this disease and effective management protocols. Treatment options may include a broad spectrum of surgical interventions, from minimally invasive resection to radical cystectomy, depending on the location, size and symptoms associated with the tumour. To date, few cases of leiomyoma have resulted in recurrence after removal, and zero have reported malignant transformation. Described here in detail is a woman in her early 40s who presented with a history of chronic pelvic pain and irregular vaginal bleeding. The urology team completed further evaluation after imaging discovered a concerning bladder lesion. Eventually, she underwent transurethral resection, with the subsequent pathology revealing a rare diagnosis of leiomyoma in the urinary bladder.	bladder
Unveiling the challenges of UTUC biopsies and cytology: insights from a global real-world practice study.	PURPOSE: Diagnostic ureteroscopy (dURS) is optional in the assessment of patients with upper tract urothelial carcinoma (UTUC) and provides the possibility of obtaining histology. METHODS: To evaluate endoscopic biopsy techniques and outcomes, we assessed data from patients from the CROES-UTUC registry. The registry includes multicenter prospective collected data on diagnosis and management of patients suspected having UTUC. RESULTS: We assessed 2380 patients from 101 centers. dURS with biopsy was performed in 31.6% of patients. The quality of samples was sufficient for diagnosis in 83.5% of cases. There was no significant association between biopsy techniques and quality (p = 0.458). High-grade biopsy accurately predicted high-grade disease in 95.7% and high-risk stage disease in 86%. In ureteroscopic low-grade tumours, the prediction of subsequent low-grade disease was 66.9% and low-risk stage Ta-disease 35.8%. Ureteroscopic staging correctly predicted non-invasive Ta-disease and ≥ T1 disease in 48.9% and 47.9% of patients, respectively. Cytology outcomes did not provide additional value in predicting tumour grade. CONCLUSION: Biopsy results adequately predict high-grade and high-risk disease, but approximately one-third of patients are under-staged. Two-thirds of patients with low-grade URS-biopsy have high-risk stage disease, highlighting the need for improved diagnostics to better assess patient risk and guide treatment decisions. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (ClinicalTrials.gov NCT02281188; https://clinicaltrials.gov/ct2/show/NCT02281188 ).	bladder
[Efficacy of combined treatment with pirfenidone and PD-L1 inhibitor in mice bearing ectopic bladder cancer xenograft].	OBJECTIVE: To assess the efficacy of pirfenidone combined with PD-L1 inhibitor for treatment of bladder cancer in a mouse model and its effect on tumor immune microenvironment modulation. METHODS: Forty C57BL/6 mouse models bearing ectopic human bladder cancer xenografts were randomized into control group, PD-L1 inhibitor group, pirfenidone group and combined treatment group (n=10). After successful modeling, PD-L1 inhibitor treatment was administered via intraperitoneal injection at 12.5 mg/kg every 3 days, and oral pirfenidone (500 mg/kg) was given on a daily basis. The survival rate of the mice and tumor growth rate were compared among the 4 groups. The expressions of CD3, CD8, CD45, E-cadherin and N-cadherin in the tumor tissues were detected with immunohistochemistry after the 21-day treatment, and bone marrow-derived suppressor cells (MDSCs) were observed with immunofluorescence staining; serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea nitrogen (BUN), creatinine (CRE) and lactate dehydrogenase (LDH-L) were analyzed using an automated biochemical analyzer. RESULTS: Treatment with PD-L1 inhibitor and pirfenidone alone both significantly decreased tumor growth rate and tumor volume at 21 days (P < 0.05), but the combined treatment produced an obviously stronger inhibitory effect (P < 0.05). PD-L1 inhibitor and pirfenidone alone significantly increased E- cadherin expression and decreased N-cadherin expression in the tumor tissue (P < 0.05). The two treatments both significantly increased the percentage of CD3(+), CD8 and CD45(+) T cells and decreased the percentage of Ly-6G(+)CD11b(+)MDSCs in the tumor tissue, and these changes were more obvious in the combined treatment group (P < 0.05). No significant differences were found in serum ALT, AST, BUN, CRE or LDH-L levels among the 4 groups (P>0.05). CONCLUSION: Combined treatment with pirfenidone and PD-L1 inhibitor significantly inhibits the progression of bladder cancer in mice possibly by regulating tumor immune microenvironment and inhibiting epithelial-mesenchymal transition of the tumor cells.	bladder
The RNA-binding protein sorbin and SH3 domain-containing 2 are transcriptionally regulated by specificity protein 1 and function as tumor suppressors in bladder cancer by stabilizing tissue factor pathway inhibitor.	Sorbin and SH3 domain-containing 2 (SORBS2) is an RNA-binding protein and has been implicated in the development of some cancers. However, its role in bladder cancer (BC) is yet to be established. The expression of SORBS2 in BC tissues was determined from the Gene Expression Omnibus and Gene Expression Profiling Interactive Analysis databases and collected paired tumor/normal samples. The effects of SORBS2 on BC cells were detected by CCK-8, colony formation, Transwell, dual-luciferase, RNA immunoprecipitation, chromatin immunoprecipitation, and DNA pull-down assays. In vivo, BC cell growth and metastasis were studied by a xenograft subcutaneous model and a tail-vein metastasis model. The results showed that SORBS2 expression was significantly decreased in BC tissues and cells. SORBS2 overexpression inhibited cell proliferation, migration, invasion, and epithelial-mesenchymal transition in vitro and tumor growth and metastasis in vivo, while silencing SORBS2 produced the opposite effect. Mechanistically, we found that SORBS2 enhanced the stability of tissue factor pathway inhibitor (TFPI) mRNA via direct binding to its 3' UTR. Restoration of TFPI expression reversed SORBS2 knockdown-induced malignant phenotypes of BC cells. In addition, SORBS2 expression was negatively regulated by the transcription factor specificity protein 1 (SP1). Conversely, SORBS2 can be transcriptionally regulated by SP1 and inhibit BC cell growth and metastasis via stabilization of TFPI mRNA, indicating SORBS2 may be a promising therapeutic target for BC.	bladder
